Lecture 2 - Physics Computation and information

There are many deep connections between cutting-edge computing and cutting-edge physics. Wonderfully ingenious engineering, based on sophisticated physics, goes into making the hardware – and some of the software, too. In the other direction, computing allows us to address questions in physics that would otherwise be unapproachable. Beyond these mutual “applications”, we’ve also come to understand that information, as well as matter, is a primary ingredient of physical reality and an -indispensable part of physics.
